Logbook helps to keep, organise and export information on analogue photography. It extends the idea of the exposure sheet, i.e. a record detailing all aspects of a given photograph. The emphasis is on the material and procedural side of film photography, where each entry can be understood as a structured note about how a specific image was created, including the equipment and exposure settings used as well as the development process.

In this sense, the app functions like a hybrid between a diary and a technical record for analogue practice. It helps track the full workflow of film photography – from exposure on different film stocks through development – while also preserving the context of when and where images were made. The result is a transparent, cumulative archive of photographic practice that highlights experimentation, consistency, and the evolving nature of working with film over time.
